T() ALL WHOM IT MAY GONCERN:

Be it known that I, EDWARD DORAN, of the city of Philadelphia, in theState of Pennsylvania, have invented a new and useful Device 4forTwisting Fringe-Loops in the Loom; and I do hereby declare that thefollowing is a full, clear, and exact description oi' the' constructionand operation of the same, reference being had to the accompanyingdra-wings, in whichvFigure 1'is a verticaltransversc section of afringeloom frame, showing my invention applied thereto, and

Figure 2 a plan view of the same- Like letters of reference indicatingth'e same parts when in both gures. The object of my invention is toatl'ord a device of more simple'and inexpensive construction andapplication, whereby the twists required lin the loops of the fringe areautomatically produccd'in a perfect manner as the said fringe is beingwoven in the loom; and my invention consists in the application to afringe-loom of mechanical devices constructed and operatingsubstantially4 as hereinafter described.

Referring to the drawings. A represents the main frame of the loom.; B,the lay of the same; C, the leverl for operating the lay B by hand; D,the shuttle; E, the loop-bar; F,- the fringe being woven, and -G thecord, on a spool'in the shuttleD. These parts are substantially the samein construction and mode of operation as in all fringe-looms.

The Anew devices are as follows, viz: H is' a bracket, which isadjustablylxed to the frame A, and supports, in a horizontal position,an adjustable plate, I, and also -a vertical arm, K, and a loosetrigger, L', L is a small grooved pulley, fixed on an arbor, whichrotatesvin the inner end of plate I, and carries around with it aslender `tapering arm, Z, which is fixed rigidly at a right angle to thesaid arbor. Mis a thin vertical plate, projecting back from the end of astem, m', which is made to slide horizontally in the plate I, and isjointed by a bar, lo, to the vertical lever K, and has also, arrangedaround its outer end, a spiral spring, m, one end of which abuts againstthe plate I, and the other end against a shoulder or pin on the outerend ofm. The thin vertical plate M has an open horizontal slot, m",extending from its centre, and widening outward, (see iig. 1,) and whenthe plate is at rest its open centre is directly opposite to the yend ofthe arbor which carries the slender arm l. O is a pawl, which catches ina ratchet-tooth in the periphery of the pulley L, arranged so as to stopthe rotary motion of the said pulley L, when the latter is running inone direction, (as will be explained,) and the arm l', on its'arbor,reaches the horizontal position shown in the drawings. P is a largegrooved pulley, supported on an upright, p', and connected, byacrossingcord,p, with the small pulley L. Attached to the pulley P thereis another pulley of smaller size, Q, around in the groove of which acord, g', p asses once or twice, and has its inner end attached to thelay B, whilst from its outer end a weight, q, is suspended. The loop-barE has its outer end pivoted to the rear part of the frame A, whilst itsinner end extends forward nearly into contact with the arbor of thepulley L, yet so that the arm Z thereon will pass it freely, (see fig.2,)and while in the position shown in the drawings, the shuttle D willpass freely across over it, but when elevated, as indicated by thedottediincs V W, the said shuttle will pass freely across under it, thesaid bar E being raised and lowered by the movement of the inearestheddle, (not shown,) it being connected therewith by a cord or otherwisefor the purpose. Y

Operation: As the layB is moved backward, the shed of the chainF opens,and the shuttle D passes either over or under tbc bar E, the latterbeing lowered and raised alternately for the purpose by the attachedheddle, and thus causes the cord G, which is connected with the spool inthe shuttle D, to pass from the chain Fof the fringe, with which it isalso connected, around the said bar E. As the lay B is moved forward,the shed closes, the bar E is lowered to its original horizontalposition, and the loop or cord G on the latter pushed ot of the said barand on to thextapering arm Z of the arbor to which the pulleyL is xed.The said arm l having been brought into the proper position (shown inthe drawings) by the previous backward movement of the lay, the weight gdrawing the pulley-cord g until the rotary motion of the pulley L issuddenly stopped by the pawl O, as the latter-'falls into theratchet-notch or tooth in the said pulley L. On the backward movement ofthe lay B, the pulley L is: rapidly rotated, and thus twists the loop ofcord on the arm l', and on ,the return -movement of the 1ayB,a smallprojection, r, ou the said lay, pulls forward the lower end of thetrigger k. and thus pushes back the lever-arm K, and consequently theslotted plate M, so as to cause the latter to push the twisted loop offof the tapered arm Z.

It will therefore be seen that this twisting-device operatesautomatically, when kept i motion by the movements of the loom, andeiectually puts'the required twists in the loops of the fringe, as thesame are successively formed around and discharged. from the looping-barE upon the arm l', during the Weaving of the fringe; that the latterwill be in a perfectly-finished condition when taken out of the loom,and that the device is simple and inexpensive of construction, and canbe readily' applied to any of the fringe-looms inuse.

I am aware that the loops for bullion fringe have before beenautomatically twisted by complicated and expensive devices applied tothe loom, as in the English patents of Livcsey and of Brooman;therefore, I do not desire to claim broadly the automatically twistingof the said loops in a loom; but, having fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is confinedto the following, viz Y l. The pulley L, with its ratchet-tooth ornotch, in combination with the pawl O, and the arbor with its arm l',the said parts being constructed, arranged, and operated by the cord p,pulleys P and Q, cord q', Weight g, and the lay B, as and for thepurposes described.

2. The slotted plate M, stem m', spring m,tbar lc, and lever Krthe saidparts being arranged and supported so as to be operated together, bymeans of the said spring m, trigger c, and the projection r on the lay,or their equivalents, substantially as and for the purpose described.
